NEW YORK, April 16 (Reuters) - Wall Street added to gains on Monday while oil and government bond prices fell on the view that this weekend’s U.S.-led missile strikes on Syria were unlikely to mark the start of a broader conflict.

Saturday’s strikes were the biggest intervention by Western countries against Syrian President Bashar al-Assad and his ally Russia, which is facing further economic sanctions over its role in the conflict.

“There is a feeling (in the market) that there will be no follow-up action,” Rabobank fixed income analyst Lyn Graham-Taylor said.

The Dow Jones Industrial Average rose 245.75 points, or 1.01 percent, to 24,605.89, the S&P 500 gained 25.42 points, or 0.96 percent, to 2,681.72 and the Nasdaq Composite added 59.34 points, or 0.83 percent, to 7,165.99.

“The action was well-received ... and that’s giving a chance for investors to focus on macro news and earnings,” said Peter Cardillo, chief market economist at Spartan Capital Securities in New York.

Healthcare shares also rose after positive updates on a cancer drug from Merck, whose shares were up 2.4 percent.

Hopes that the strike against Syria would not escalate further also spurred investors to shed the U.S. dollar.
